Have been researching mezz cues and have decided to get one.The ones i like are the ec7 series and the aya-k. I also found the axi line on j&j site.My question is,for someone who likes alot of feedback from his shot,which is better. The aya-k had the united joint with aegis collar,the ec7 also has that joint with a different collr and the axi has the wavy joint with the aegis collar.
